Molly Fish With Hunched Back?

[Rollxr]

Hi everyone, the following picture with a red mark is a picture from 6 months ago. And the other picture with a blue mark, is a picture from today. Has my molly’s back and tail bended or worsened? Is he fine??

Dang, that's weird...honestly I don't know what to say other than it's possible it did skeletal damage, and as it's grown, it's gotten worse.

Just a theory, I don't even know if like the fish jumped out of the tank or what...hopefully someone else here has a better answer
